Problems solved by technology
[0006] At present, the optical fiber coating layer coating is mainly composed of ultraviolet light-curable multifunctional acrylate. When it is cured by ultraviolet light, its absorption and utilization of ultraviolet light are not enough, which slows down the efficiency and speed of ultraviolet light curing. For high-speed wire drawing In other words, without changing the original optical fiber coating coating formula, it needs to increase the ultraviolet radiation power to meet the curing process requirements of the optical fiber coating coating during fast drawing
